When Roof Replacement Is A Better Option Than Reroofing

Construction & Contractors Blog

A new roof is a huge investment in your home, so you probably want to save as much money as you can. You may wonder if re-roofing is a good way to repair your roof while cutting costs. Roofing contractors can give you a quote for re-roofing vs roof replacement and advise you on which is the best option for your home. Here are some situations where adding a new layer of asphalt shingles might not be the best way to go:

Your Roof Has Two Layers Already

Building codes limit homes to two layers of roofing. This is mainly due to the weight of the roof on your home. Asphalt shingles may not seem heavy, but when there are more than two layers piled on top of your roof, the accumulated weight can be more than some houses can support. If your home is several decades old, it's possible a previous owner had a second layer of roofing applied at one time.

When your roof is inspected, the contractor will check for multiple layers of shingles, and if there are already two, you'll need to tear them both off and start with a new roof from scratch. Even if your roof only has one layer of shingles, that doesn't always mean adding a new layer is a suitable option.

Many Shingles Are Curled Or Damaged

Reroofing is best suited for old roofs that are still in pretty good shape. If your current roof has many damaged shingles, it may not be possible to add new shingles on top of them. One problem with old shingles is that the edges will start to curl up. When this happens, new shingles can't be attached so they are completely flat, and that increases the risk of water leaking. If your roof is being replaced due to old age, it will probably be more suitable for re-roofing than a roof that is being replaced due to storm damage.

The Deck Is Decayed Or Damaged

When you have a second layer of roofing shingles applied, the first layer of shingles and the deck underneath stay in place. If the deck is damaged due to a water leak, it has to be pulled up and replaced. If it is just covered over, the wood will continue to decay and that will drastically shorten the life of your new roof. One potential problem with re-roofing is that the contractor can't actually look at the deck to examine it. Walking on the roof tests it for strength and checking the underside in the attic for leaks gives some clues, and if deck damage is suspected, then it's better to pull off the old roof and replace the deck before putting on new shingles.

Another thing to ask your roofing contractor about is the expected lifespan of a reroof compared to a roof replacement. If you'll have to replace the roof sooner, then saving money initially by reroofing may actually cost more money in the end.
